Use of telemedicine and telephone consultation in decision-making and follow-up of burn patients: Initial experience from two burn units

Virtual burn care - Friend or foe? A systematic review

INTRODUCTION

Evidence on the impact of virtual care for patients with burn injuries is variable. This review aims to evaluate its use in remote assessment, rounding, and follow-up through outcomes of efficacy, usability, costs, satisfaction, clinical outcomes, impacts on triage and other benefits/drawbacks.

METHODS

A PRISMA-compliant qualitative systematic review (PROSPERO CRD42021267787) was conducted in four databases and the grey literature for primary research published between 01/01/2010 and 12/31/2020. Study quality was appraised using three established tools. Evidence was graded by the Oxford classification.

RESULTS

The search provided 481 studies, of which 37 were included. Most studies (n = 30, 81%) were Oxford Level 4 (low-level descriptive/observational) designs and had low appraised risk-of-bias (n = 20, 54%). Most applications were for the acute phase (n = 26, 70%). High patient compliance, enhanced specialist access, and new educational/networking opportunities were beneficial. Concerns pertained to IT/connection, virtual communication barriers, privacy/data-security and logistical/language considerations. Low-to-moderate-level (Oxford Grade C) evidence supported virtual burn care's cost-effectiveness, ability to improve patient assessment and triage, and efficiency/effectiveness for remote routine follow-up.

CONCLUSION

We find growing evidence that virtual burn care has a place in acute-phase specialist assistance and routine outpatient follow-up. Low-to-moderate-level evidence supports its effectiveness, cost-effectiveness, usability, satisfactoriness, and capacity to improve triage.

Barriers to Remote Burn Care Delivery: An Analysis of Burn Center Proximity and Access to Critical Telehealth Infrastructure

ABSTRACT

Mounting evidence supports the use of telehealth to improve burn care access and efficiency. However, barriers to telehealth use remain throughout the United States and may disproportionately affect specific populations, such as rural and non-English-speaking patients. This study analyzes the association between physical proximity to burn care and determinants of telehealth access.The relationship between telehealth-associated measures and proximity to burn care was analyzed with linear regression analysis. County-level data was sourced from the Agency for Healthcare Research and Quality's Social Determinants of Health Database (2020) and the American Community Survey (2021). County-level distances to the nearest American Burn Association (ABA)-verified burn center were calculated based on verified centers listed in the ABA burn center directory (n = 59). A subsequent analysis was performed on income-stratified datasets available for subset counties.Distance was negatively correlated with access to a smartphone (P < 0.0001), broadband internet (P < 0.0001), and cellular data plan (P < 0.0001) and positively correlated with the percent of households with no computing device (P < 0.0001) and no internet access (P < 0.0001). Analysis of income-stratified data revealed similar results. The percent population not speaking English well (P < 0.0001) at all (P = 0.0009) and the proportion of limited English-speaking households (P = 0.0001) decreased as a function of distance.People living furthest from an ABA-verified burn center in the United States are less likely to have adequate access to critical telehealth infrastructure compared to their counterparts living closer to a burn center. However, income impacts overall access and the degree to which access changes with proximity. Conversely, language-associated barriers decrease as distance increases.

Impact of Tele-Triage Pathways on Short-Stay Admission after Transfer to a Regional Burn Center for Acute Burn Injury

BACKGROUND

Regionalized care for burn-injured patients requires accurate triage. In 2016, we implemented a tele-triage system for acute burn consultations. We evaluated resource utilization following implementation, hypothesizing that this system would reduce short-stay admissions and prioritize inpatient care for those with higher burn severity.

STUDY DESIGN

We conducted a retrospective study of all transferred patients with acute burn injuries from January 1, 2010 to December 31, 2015, and January 1, 2017 to December 31, 2019. We evaluated the proportions of short-stay admissions (discharges less than 24 hours without operative intervention, ICU admission, or concern for nonaccidental trauma) among patients transferred before (2010 to 2015) and after (2017 to 2019) triage system implementation. Multivariable Poisson regression was used to evaluate factors associated with short-stay admissions. Interrupted time series analysis was used to evaluate the effect of the triage system.

RESULTS

There were 4,688 burn transfers (3,244 preimplementation and 1,444 postimplementation) in the study periods. Mean age was higher postimplementation (32 vs 29 years, p < 0.001). Median hospital length of stay (LOS) and ICU LOS were both 1 day higher, more patients underwent operative intervention (19% vs 16%), and median time to first operation was 1 day lower postimplementation. Short-stay admissions decreased from 50% (n = 1,624) to 39% (n = 561), and patients were 17% less likely to have a short-stay admission after implementation (adjusted relative risk [aRR], 0.83; 95% CI, 0.8 to 0.9). Pediatric patients younger than 15 years old composed 43% of all short-stay admissions and were much more likely than adult patients to have a short-stay admission independent of transfer timing (aRR, 2.36; 95% CI, 1.84 to 3.03).

CONCLUSIONS

Tele-triage burn transfer center protocols reduced short-stay admissions and prioritized inpatient care for patients with more severe injuries. Pediatric patients remain more likely to have short-stay admission after transfer.

Applications, opportunities, and challenges in using Telehealth for burn injury management: A systematic review

INTRODUCTION

Burns are global public health devastating and life-threatening injuries. Telehealth can be an appropriate answer for the effective utilization of health care resources, prevention referrals and reduce socio-economic burden of burns injuries. Thus, this study aimed to systematically evaluate the applications, opportunities, and challenges of using telehealth in burn injuries management.

METHODS

A structured search was conducted according to PRISMA statement guidelines in the Web of Science, PubMed, Scopus, and Science Direct as well as the Google Scholar for studies published until June 28, 2022. Of the total 2301 yielded studies, 36 articles were included in the final review. Quality appraisal was done according to the Mixed Methods Appraisal Tool (MMAT) version 2018. Thematic analysis was applied for data analysis.

RESULTS

Patient triage, transfer, and referral (38.9%) follow-up (22%), care (22%), consultation (9%), education (3%), and rehabilitation (3%) were the most prevalent application of telehealth, respectively. Our findings identified 72 unique concepts, eight initial themes, and two clinical and administrative final themes for opportunities of using telehealth in burn injury management. Furthermore, we identified 27 unique concepts, three initial themes, and two clinical and administrative final themes for remaining challenges.

CONCLUSIONS

Despite providing pivotal opportunities such as improving burn injury diagnosis and quality of care, increasing patient and provider satisfaction, and cost containment using telehealth in burn injuries management, the concept faces challenges such as the impossibility of the physical examination of patients and technological difficulties. Our findings provide valuable information for policymakers and decision-makers infield of burn injuries and effective planning for using telehealth technology.

Reliability, Validity, and Predictive Validity of Cutaneous Functional Units Predicted to Scar Following Palmar Burn Injury in Young Children

Identification of children at risk of palmar burn scar is important for early initiation of scar management. This study determined the interrater reliability of face-to-face and photographic assessments of 29 palmar cutaneous functional units (CFUs) predicted to scar following palmar burn. The validity of photographic compared to face-to-face assessment, and the predictive validity of both assessment types to identify scarring at 3 to 6 months following burn, was also established. Thirty-nine children (40 hands) post burn injury were assessed face-to-face in the clinical setting, following healing of their palmar burn, by three burn therapists. Photographs of the children's hands at initial assessment were assessed by the same therapists a minimum of 6 months later. To determine which CFUs scarred, children were reassessed face-to-face in the clinical setting 3 to 6 months following their burn. For analysis, 29 CFUs were merged into eight separate groups to determine the number of CFUs predicted to scar per CFU group for face-to-face and photographic assessments. The range of agreement for individual CFUs within CFU groups was also calculated for both assessment types. Excellent interrater reliability was established for face-to-face assessment in all eight CFU groups (ICC2,1 0.83-0.96). Photographic assessment demonstrated good to excellent interrater reliability in six CFU groups (ICC2,1 0.69-0.90) and validity in seven CFU groups (ICC2,1 0.66-0.87). Good to excellent predictive validity was established for both assessment types in seven CFU groups (face-to-face ICC2,1 0.60-0.95, photographic ICC2,1 0.69-0.89). Experienced therapists can reliably assess CFUs face-to-face or via photographs and predict future scar development.

Utility of Telehealth Platforms Applied to Burns Management: A Systematic Review

The financial burden of burn injuries has a considerable impact on patients and healthcare systems. Information and Communication Technologies (ICTs) have demonstrated their utility in the improvement of clinical practice and healthcare systems. Because referral centres for burn injuries cover large geographic areas, many specialists must find new strategies, including telehealth tools for patient evaluation, teleconsultation, and remote monitoring. This systematic review was performed according to PRISMA guidelines. PubMed, Cochrane, Medline, IBECS, and LILACS were the search engines used. Systematic reviews, meta-analyses, clinical trials, and observational studies were included in the study search. The protocol was registered in PROSPERO with the number CRD42022361137. In total, 37 of 185 studies queried for this study were eligible for the systematic review. Thirty studies were comparative observational studies, six were systematic reviews, and one was a randomised clinical trial. Studies suggest that telehealth allows better perception of triage, more accurate estimation of the TBSA, and resuscitation measures in the management of acute burns. In addition, some studies assess that TH tools are equivalent to face-to-face outpatient visits and cost-efficient because of transport savings and unnecessary referrals. However, more studies are required to provide significant evidence. However, the implementation of telehealth should be specifically adapted to each territory.

A six-week physical therapy exercise program delivered via home-based telerehabilitation is comparable to in-person programs for patients with burn injuries: A randomized, controlled, non-inferiority clinical pilot trial

BACKGROUND

Exercise programmes are essential for burn rehabilitation, however patients often have barriers accessing these services. Home-based telerehabilitation (HBT) may be an alternative. This study aimed to determine if exercise programs delivered via HBT were as effective as in-person (IP) programs with respect to clinical outcomes and participant and therapist satisfaction.

METHODS

A single center, randomized, controlled, non-inferiority pilot trial with blinded assessment was undertaken. Forty-five adults with ≤ 25% total body surface area (TBSA) burns were randomized to receive a 6-week exercise program delivered either by HBT or IP. The primary outcome was burn-specific quality of life (Burn Specific Health Scale - Brief). Secondary outcomes included health-related quality of life, burn scar-specific outcomes, exercise self-efficacy, pain severity, muscle strength and range of motion (ROM). Participant and therapist satisfaction, technical disruptions and adverse events were also recorded.

RESULTS

We found no significant within- or between-group differences for any outcome measures except ROM. Achievement of full ROM was significantly different between groups at Week 12 (IP=100% vs HBT=70%, p = 0.005). Non-inferiority was inconclusive. Participant satisfaction was high (median ≥ 9.8/10), with no significant between-group differences. Therapist satisfaction was high (median ≥ 8.9/10), major technical disruptions low (8%) and no adverse events reported.

CONCLUSION

HBT is a safe, effective option to deliver exercise programs for patients with burn injuries ≤ 25% TBSA with comparable clinical outcomes to in-person programmes. Ongoing research is required to further analyze ROM and investigate the effectiveness of HBT for patients with larger burns.

Outcomes of Telehealth for Wound Care: A Scoping Review

OBJECTIVE

To synthesize the literature on delivering wound care via telehealth and compare clinical, healthcare utilization, and cost outcomes when wound care is provided via telehealth (telewound) modalities compared with in-person care.

DATA SOURCES

An electronic search of PubMed, CINAHL, and Cochrane Clinical Trials databases for articles published from 1999 to 2019 was conducted using the following MeSH search terms: telewound, wound, wound care, remote care, telehealth, telemedicine, eHealth, mobile health, pressure injury, and ulcer.

STUDY SELECTION

Articles were included if they were a scientific report of a single study; evaluated a telehealth method; identified the type of wound of focus; and provided data on clinical, healthcare utilization, or cost outcomes of telewound care. In total, 26 articles met these criteria.

DATA EXTRACTION

Data were extracted and grouped into 13 categories, including study design, wound type, telehealth modality, treatment intervention, and outcomes measured, among others.

DATA SYNTHESIS

Of the 26 studies, 19 reported on clinical outcomes including overall healing and healing time; 17 studies reported on healthcare utilization including hospitalizations and length of stay; and 12 studies reported costs.

CONCLUSIONS

Evidence regarding the use of telewound care is weak, and findings related to the impact of telewound care on outcomes are inconsistent but indicate that it is not inferior to in-person care. Greater use of telehealth as a result of the COVID-19 pandemic points to further development of navigation and education models of telehealth for wound care. However, additional studies using rigorous research design and leveraging robust sample sizes are needed to demonstrate value.

Telemedicine in Surgical Care in Low- and Middle-Income Countries: A Scoping Review

Background

Access to timely and quality surgical care is limited in low- and middle-income countries (LMICs). Telemedicine, defined as the remote provision of health care using information, communication and telecommunication platforms have the potential to address some of the barriers to surgical care. However, synthesis of evidence on telemedicine use in surgical care in LMICs is lacking.

Aim

To describe the current state of evidence on the use and distribution of telemedicine for surgical care in LMICs.

Methods

This was a scoping review of published and relevant grey literature on telemedicine use for surgical care in LMICs, following the PRISMA extension for scoping reviews guideline. PubMed-Medline, Web of Science, Scopus and African Journals Online databases were searched using a comprehensive search strategy from 1 January 2010 to 28 February 2021.

Results

A total of 178 articles from 53 (38.7%) LMICs across 11 surgical specialties were included. The number of published articles increased from 2 in 2010 to 44 in 2020. The highest number of studies was from the World Health Organization Western Pacific region (n = 73; 41.0%) and of these, most were from China (n = 69; 94.5%). The most common telemedicine platforms used were telephone call (n = 71, 39.9%), video chat (n = 42, 23.6%) and WhatsApp/WeChat (n = 31, 17.4%). Telemedicine was mostly used for post-operative follow-up (n = 71, 39.9%), patient education (n = 32, 18.0%), provider training (n = 28, 15.7%) and provider-provider consultation (n = 16, 9.0%). Less than a third (n = 51, 29.1%) of the studies used a randomised controlled trial design, and only 23 (12.9%) reported effects on clinical outcomes.

Conclusion

Telemedicine use for surgical care is emerging in LMICs, especially for post-operative visits. Basic platforms such as telephone calls and 2-way texting were successfully used for post-operative follow-up and education. In addition, file sharing and video chatting options were added when a physical assessment was required. Telephone calls and 2-way texting platforms should be leveraged to reduce loss to follow-up of surgical patients in LMICs and their use for pre-operative visits should be further explored. Despite these telemedicine potentials, there remains an uneven adoption across several LMICs. Also, up to two-thirds of the studies were of low-to-moderate quality with only a few focusing on clinical effectiveness. There is a need to further adopt, develop, and validate telemedicine use for surgical care in LMICs, particularly its impact on clinical outcomes.

Inappropriate Transfer of Burn Patients: A 5-Year Retrospective at a Single Center

OBJECTIVE

Burn injuries have an annual incidence exceeding 40,000. The Burn Center Referral Criteria published by the American Burn Association (ABA) serve to guide health centers in determining appropriateness of patient transfer to a specialized center. With inappropriate transfer rates reaching up to 77%, reliance on the ABA criteria is critical as the decision to transfer a patient can impose significant costs to both the patient and healthcare system. The aim of this study is to evaluate the appropriateness of all burn patient transfers to a single burn center over a 5-year period and assess the potential role of telemedicine to optimize the assessment and care of this patient population.

METHODS

A 5-year retrospective review was conducted to all burn patients transferred or consulted for transfer to our burn center between January 2013 and January 2017. After application of inclusion and exclusion criteria, 767 cases were analyzed, with 612 ultimately being transferred. Outcome measures included basic clinical and demographic information, as well as logistical burn and transfer data such as percent total body surface area and transfer distance. After data collection, 5-year descriptive trends were analyzed, and the ABA criteria were applied to each patient case to evaluate appropriateness of transfer. Patients transferred despite not meeting at least one of the ABA criteria were classified as inappropriately transferred.

RESULTS

A total of 25 patients (3.2%) were found to be inappropriate transfers. Statistical analysis compared appropriately transferred patients (n = 587) with those inappropriately transferred. Overall, inappropriately transferred patients were more likely to have superficial partial thickness burns (76% vs 46%, P = 0.05), were less likely to need surgery (4% vs 22%, P < 0.05), and had a higher incidence of upper extremity burns (32% vs 4%, P < 0.01).

CONCLUSIONS

Our study increases awareness of the most commonly seen presentation of inappropriately transferred burn patients over a 5-year period at our center. Given the advent of telemedicine, the ability of institutions to pinpoint a subset of patients most vulnerable to inappropriate transfer will allow for a streamlining of resources that will serve to benefit both patients and the health system.

Early clinical management of severe burn patients using telemedicine: a pilot study protocol

Background

Emergency physicians are responsible for assessing the severity of a patient's burns, which determines whether the patient needs to be transferred to a burn center. Such a proper assessment represents a daunting task because severe burn injuries are rare. Inaccurate estimates often result in unjustified and costly transfers and unneeded fluid resuscitation and assisted ventilation procedures. Telemedicine offers a solution to these challenges. The present pilot study aims to investigate the feasibility, acceptability, and potential value of a large telemedicine initiative at the University of Montreal Health Center's burn center and its network of referring hospitals.

Methods

A three-stage study protocol is proposed to achieve this objective. First, a proof of concept phase will assess the technical feasibility of telemedicine at one referring hospital with a high volume of patient transfers. Second, the organizational and human feasibility of the project will be evaluated in four referring medical centers. All teleconsultation sessions will be analyzed using the WHO's telemedicine implementation model. The third phase will consist of evaluating the potential impacts of telemedicine in a subset of 10 referring hospitals. The quality of communications between referring physicians and specialists will be assessed using semi-structured interviews. A pre-test/post-test with a comparison group design will be used to assess the effects of telemedicine on patient transfers, ventilation procedures, patient complications, mortality, length of ICU stay, and additional surgical procedures. The economic viability of telemedicine will be assessed using a cost-minimization approach.

Discussion

The telemedicine initiative is expected to yield positive and significant outcomes that are relevant to a wide range of medical centers that already use or are considering using a similar technology. The contribution of this pilot study lies in its ability to reveal technological, organizational, and human barriers and provide a preliminary assessment of the clinical and economic value of a large-scale telemedicine initiative in the context of burn medicine.

Teleconsultation Using Mobile Phones for Diagnosis and Acute Care of Burn Injuries Among Emergency Physicians: Mixed-Methods Study

Background

The referral process in acute care remains challenging in many areas including burn care. Mobile phone apps designed explicitly for medical referrals and consultations could streamline the referral process by using structured templates and integrating features specific to different specialties. However, as these apps are competing with commercial chat services, usability becomes a crucial factor for successful uptake.

Objective

The aim of this study was to assess the usability of a mobile phone app for remote consultations and referrals of burn injuries.

Methods

A total of 24 emergency doctors and 4 burns consultants were recruited for the study. A mixed-methods approach was used including a usability questionnaire and a think-aloud interview. Think-aloud sessions were video-recorded, and content analysis was undertaken with predefined codes relating to the following 3 themes: ease of use, usefulness of content, and technology-induced errors.

Results

The users perceived the app to be easy to use and useful, but some problems were identified. Issues relating to usability were associated with navigation, such as scrolling and zooming. Users also had problems in understanding the meaning of some icons and terminologies. Sometimes, some users felt limited by predefined options, and they wanted to be able to freely express their clinical findings.

Conclusions

We found that users faced problems mainly with navigation when the app did not work in the same way as the other apps that were frequently used. Our study also resonates with previous findings that when using standardized templates, the systems should also allow the user to express their clinical findings in their own words.

Teleburn: Designing A Telemedicine Application to Improve Burn Treatment

Background

Due to the increasing rate of the burn injuries and a limited number of specialized treatment centers, providing medical advice and medical care at the point of need is necessary. The aim of the present study was to design and implement a teleburn system to enhance the quality of care for the burn patients.

Methods

This study was completed in 2016. In order to design the system, information needs assessment was conducted by using a questionnaire. The participants of this phase were five specialists, five general practitioners, and 12 nurses. The setting of the study was the burn department of a public hospital and a burn center. The prototype of the system was designed based on the findings derived from the first phase, and the usability of the system was evaluated later.

Results

The teleburn system was a web-based system with different sections for GPs/nurses and specialists. In total, 28 burn consultations were made successfully by using the system. The findings of the usability testing showed that most of the participants evaluated the system at a good level. The mean score for the specialists, general practitioners and nurses was 8.4±0.46, 7.7±0.39, and 7.5±0.51, respectively.

Conclusion

Although it was the first time in the country that the teleburn system was designed and introduced to the clinicians, they seemed to be satisfied with using the system. This system could help general practitioners and nurses to receive specialist's advice on a timely manner to improve the treatment of the burn patients. However, more research should be conducted to determine the effectiveness of using this technology in the real work environment.

Expectations of medical specialists about image-based teleconsultation - A qualitative study on acute burns in South Africa

BACKGROUND

Image-based teleconsultation between medical experts and healthcare staff at remote emergency centres can improve the diagnosis of conditions which are challenging to assess. One such condition is burns. Knowledge is scarce regarding how medical experts perceive the influence of such teleconsultation on their roles and relations to colleagues at point of care.

METHODS

In this qualitative study, semi-structured interviews were conducted with 15 medical experts to explore their expectations of a newly developed App for burns diagnostics and care prior to its implementation. Purposive sampling included male and female physicians at different stages of their career, employed at different referral hospitals and all potential future tele-experts in remote teleconsultation using the App. Positioning theory was used to analyse the data.

RESULTS

The experts are already facing changes in their diagnostic practices due to the informal use of open access applications like WhatsApp. Additional changes are expected when the new App is launched. Four positions of medical experts were identified in situations of diagnostic advice, two related to patient flow-clinical specialist and gatekeeper-and two to point of care staff-educator and mentor. The experts move flexibly between the positions during diagnostic practices with remote colleagues. A new position in relation to previous research on medical roles-the mentor-came to light in this setting. The App is expected to have an important educational impact, streamline the diagnostic process, improve both triage and referrals and be a more secure option for remote diagnosis compared to current practices. Verbal communication is however expected to remain important for certain situations, in particular those related to the mentor position.

CONCLUSION

The quality and security of referrals are expected to be improved through the App but the medical experts see less potential for conveying moral support via the App during remote consultations. Experts' reflections on remote consultations highlight the embedded social and cultural dimensions of implementing new technology.

systematized review of telemedicine applications in treating burn patients

Background: Telemedicine has been used in different fields of medicine in the past 20 years. The main advantages of this technology include saving costs, improving quality of care, and increasing access to specialists. This study aimed to review telemedicine applications in treating burn patients. Methods: In this systematized review study, related papers were searched using various databases, including PubMed, Scopus, and Science Direct. The time frame was between January 2000 and March 2016; finally, 32 papers were included in the study. Results: The findings revealed that telemedicine was used in burn care in three different ways: Remote patient follow-up, teleconsultation, and patient assessment. Conclusion: It seems that telemedicine can be easily applied in treating burn patients even when there is a limited financial resource. The use of this technology can help reduce possible errors in categorizing burn patients and decrease patients' transportation and treatment costs.

Centralized monitoring and virtual consultant models of tele-ICU care: a systematic review

BACKGROUND

Increasing intensivist shortages and demand coupled with the escalating cost of care have created enthusiasm for intensive care unit (ICU)-based telemedicine ("tele-ICU"). This systematic literature review compares the Centralized Monitoring and Virtual Consultant tele-ICU Models.

MATERIALS AND METHODS

With an experienced medical reference librarian, we identified all language publications addressing the employment and efficacy of the centralized monitoring and virtual consultant tele-ICU systems through PubMed, CINAHL, and Web of Science. We performed quantitative and qualitative reviews of documents regarding financial sustainability, clinical outcomes, and ICU staff workflow and acceptance.

RESULTS

Of 1,468 documents identified, 1,371 documents were excluded, with the remaining 91 documents addressing clinical outcomes (46 documents [enhanced guideline compliance, 5; mortality and length of stay, 28; and feasibility, 13]), financial sustainability (9 documents), and ICU staff workflow and acceptance (36 documents). Quantitative review showed that studies evaluating the Centralized Monitoring Model were twice as frequent, with a mean of 4,891 patients in an average of six ICUs; Virtual Consultant Model studies enrolled a mean of 372 patients in an average of one ICU. Ninety-two percent of feasibility studies evaluated the Virtual Consultant Model, of which 50% were in the last 3 years. Qualitative review largely confirmed findings in previous studies of centralized monitoring systems. Both the Centralized Monitoring and Virtual Consultant Models showed clinical practice adherence improvement. Although definitive evaluation was not possible given lack of data, the Virtual Consultant Model generally indicated lean absolute cost profile in contrast to centralized monitoring systems.

CONCLUSIONS

Compared with the Virtual Consultant tele-ICU Model, studies addressing the Centralized Monitoring Model of tele-ICU care were greater in quantity and sample size, with qualitative conclusions of clinical outcomes, staff satisfaction and workload, and financial sustainability largely consistent with past systematic reviews. Attention should be focused on performing more high-quality studies to allow for equitable comparisons between both models.

A home-based health information acquisition system

With the development of health consciousness and growing of the aging population, the healthcare demand becomes more and more important. At the same time, recent rapid growth in mobile computing technologies enables telemedicine applications operations on mobile devices. The technologies and demands accelerated different kinds of home-based devices for the aged healthcare and medical treatment. Our focus is on the design of an information system for in-home healthcare, and a new household acquisition terminal device which integrated electrocardiogram (ECG), blood oxygen, blood pressure and body temperature acquirement functions. A set-top box based manipulation method was adopted for operators, the physiological data could be acquired by the corresponding detectors. The parameters were collected and transmitted by set-top box and were received by the data server and sent to the medical staff of a hospital or healthcare center, professional healthcare advice or clinical diagnosis would be provided. Simultaneously, the collected parameters and the feedback clinic advice was stored on the servers which could be accessed by long distance clients such as a mobile smart phone user. The proposed system involved multiple physiologic parameters which led to great potential for universality, and in the terminal side the set-top box and IPTV screen shared scenario brought ease of use. Further progresses were made in the product upgrade because the shared IPTV screen was employed, which might be improved with the family demand. The acquirement instrument got a certification of China State Food and Drug Administration. The entire system was built for commercial achievements and the acquired data had great potential in disease screening and public hygiene research.

Telemedicine for wound management

The escalating physiological, psychological, social and financial burdens of wounds and wound care on patients, families and society demand the immediate attention of the health care sector. Many forces are affecting the changes in health care provision for patients with chronic wounds, including managed care, the limited number of wound care therapists, an increasingly ageing and disabled population, regulatory and malpractice issues, and compromised care. The physician is also faced with a number of difficult issues when caring for chronic wound patients because their conditions are time consuming and high risk, represent an unprofitable part of care practice and raise issues of liability. Telemedicine enhances communication with the surgical wound care specialist. Digital image for skin lesions is a safe, accurate and cost-effective referral pathway. The two basic modes of telemedicine applications, store and forward (asynchronous transfer) and real-time transmission (synchronous transfer, e.g. video conference), are utilized in the wound care setting. Telemedicine technology in the hands of an experienced physician can streamline management of a problem wound. Although there is always an element of anxiety related to technical change, the evolution of wound care telemedicine technology has demonstrated a predictable maturation process.

Photographic assessment of burn wounds: a simple strategy in a resource-poor setting

OBJECTIVE

To validate the use of photographic burn wound assessment in evaluation of burn size and wound characteristics.

METHODS

Feasibility study of agreement between methods of measurement of burn size and characteristics, in patients admitted to the burn unit at Kamuzu Central Hospital (KCH), Malawi, over two months in 2011. Burn wounds were photographed and assessed clinically, concurrently, by an experienced clinician. Photographs reviewed by two blinded burn clinicians after 4-6 weeks. Correlation between clinical assessment and photographic evaluation was calculated using kappa score and Pearson's correlation coefficient.

RESULTS

Thirty-nine patients were included in evaluation of TBSA, and fifty wounds assessed for their characteristics. Pearson's correlation coefficient for agreement of TBSA between clinical exam and photograph review by expert#1, and #2, was 0.96, 0.93 (p<0.001), respectively. Pearson's correlation coefficients comparing expert#1 and #2 to the gold standard were: proportion of full-thickness burn (0.88 and 0.81, p<0.001), and epithelialized superficial burn (0.89 and 0.55, p<0.001). Kappa scores were significant for wound evolution (expert#1 0.57, expert#2 0.64, p<0.001), and prognosis (expert#1 0.80, expert#2 0.80, p<0.001).

CONCLUSIONS

Burn assessment with digital photography is a valid and affordable alternative to direct clinical exam, alleviating access issues to burn care in developing countries.
